The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

PIX 515E.....Proper DMZ setup PLEASE! *************3 simple objectives****************.

Asked by ioglyphics in Application Protocols, Cisco PIX Firewall, Domain Name Service (DNS)

Tags: pix, dmz, 515e

I have been trouble shooting this for over a week now and I am nearly in tears.  I am simply trying to facilitate a DMZ (which is set up) that will allow for..........

1.access to a staging server that our clients could get to our beta version of  a web app, and allow us to get to inside our LAN, by the url and not the internal IP that has (or now maybe had)  
I know DNS here is the issue but I am certain it is in the PIX and not my DNS servers settings, but I could be wrong

2. ftp

3.front end Exchange server with OWA

I have posted my config here for you to look at.
